l To all whom t may concern:

Be it known that I, THOMAS J. GOODWIN, a ctizen of the United States, residin at Waco, in the county of McLennon and tate of Texas, have invented new and useful Improvements in Automobile-Cooling Systems, of which the following is a specification.

This invention is an improved cooling apparatus or system especially designed for' cooling the internal combustion engine of an automobile, the object of the invention being to provide an improved cooling system of this kind which embodies means for cooling the circulatory water in the radiator by forcing air therethrough'and also embodies means for directly cooling the engine by subjecting-the ysame to the action of a blast of air.

A further object of the invention is to provide an improved cooling apparatus or system of this character which is extremely cheap and simple and which can be readily installed in an automobile.

The inventionconsists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings l Figure 1 is partly an elevation and partly a sectional view .of an internal combustion cooling apparatus constructed and arranged in accordance with my invention.

Fig. 2 is an elevation of the same, at rightangles to Fig. 1 and showing the casing o the rotary fan partly removed and in section.

Fig. 3 is a vertical same.

Fig. 4 is a horizontal sectional view of the sectional view of the me. In the embodiment of my invention I provide a radiator 1 through which the waterv for cooling the engine cylinders bycirculation through the water jackets also circulates in the usual manner. The radiator is provided with a centrally arranged -inner tubular wall 2 of considerable diameter which connects the front and. rear walls ofV the radiator and is open at the ends for the passage of air therethrough. `A screen 3' covers the front end of the wall or air passage and prevents trash from passing therethrough. On the rear wall'of the radiator at opposite sides of the said air' passage are vertically arranged guide strips 4 whichhavve guide grooves 5 1n their opposing sldes.

inner tubular The casing 6 of a revoluble blower or fan 7 is provided at opposite sides with arms 8 which slidably engage in the grooves of the guide strips and hence adapt the blower or fan for -vertical movement on the rear side of the radiator, the fan casing being arranged opposite the rear end of thec'entral air passage of the radiator andbeing of less diameter than said air passage. n vthe rear side of the radiator is a lug 8. A screw 9 which is vertically arranged passes through and engages in a threaded opening of the lug, the lower end of the screw being swivelly connected as at 9a to the upper side of the casing of the fan or blower. A spring 10 is arranged around the screw and bears between the fan or blower casing and the lugl and serves to cushion the fan or blower casing vand to prevent rattling and to also exert a constant downward pressure thereon. AThe revoluble member of the fan or blower is indicated at 11 and has a shaft 12 which is mounted in bearings in the front and rear sides of the casing, the said shaft extending rearwardly from the casing and being provided with an exteriorly arranged fan 13 and also with a peripherally pulley 14, the latter being in practice connected to a corresponding pulley on the en- -gine shaft by means of an endless belt 14: so that the revoluble member of the blower fan and also the exteriorly arranged fan are both driven by the motor. the blower fan is provided with a discharge nozzle 15 whichis connected by a flexible hose 16 of suitable length with the intake end of a tube 17, said tube being arranged and extending downwardly and in one side nipple 19 is provided forathe radiator at al point a suitable distance above the level of the water therein.

Y In the operation of my invention the blast of air discharged by the fan or blower passes through the pipe 17 `and by reason of the apertures Itherein is forced through the water in the radiator, at various elevations so that the water in the` radiator is directly cooled by air jetstherethrough. The exteriorly arranged fan 13 serves to direct a blast of air directly on the exterior of the cylinders of the engine, as will be understood, so that my cooling apparatus directlycools the air by circulation through the water jackets of the grooved y The casing of the passage and forcing of thev El STATESPATENT `onirica.

required in order to keep the driving belt' tight.

My improved cooling apparatus is simple in construction, is extremely compact and may be installed in an automobile atslight cost.

While I have herein shown and described a preferred form of my invention, I would have it understood that changes may be made in the form, proportion and constructionof the several parts, without departing' from the spirit of my invention and within the 'scope of the appended claim.

Having thus described my invention, I claim v In apparatus of the class described, a

radiator having an air passage therethrough and also provided, on its rear side, with vertical grooved guide strips' at opposite sides of said opening, a blower for its casin arranged on the rear side of the radiator opposite said passage' and provided with attaching arms slidably engaged in the grooves of said strips, a duct leading from the blower casing into the radiator and terminating below the water level of the radiator, a vertical adjusting screw for the blower casing and a cushioning spring bearing downwardly on the blower casing.

In testimony whereof I THOMAS JEFFERSON GOODWIN.
